7045. 'And cut off the foreskin of her son' means the removal of filthy kinds of love, as a result of which the internal is laid bare. This is clear from the meaning of 'cutting off' as removing; from the meaning of 'the foreskin' as earthly and bodily love which defiles spiritual and celestial love, dealt with in 3412, 4462; and from the meaning of 'son' as the truth which the representative Church possesses. For the meaning of 'son' as truth, see 489, 491, 533, 1147, 2623, 3773; and the reason why the truth which that Church possesses is meant here is that 'Zipporah' represents that Church and calls him 'her son'. She also uses him to show the actual nature of that nation and consequently the actual nature of its worship. 'The foreskin' means filthy kinds of love for the following reason: The loins and genital organs correspond to conjugial love, 5050-5062; and since they correspond to conjugial love they also correspond to every kind of celestial and spiritual love, 686, 4277, 4280, 5054. The foreskin therefore corresponds to the kinds of love that are very much external, which are called bodily and earthly loves. If these loves are devoid of the internal kinds of love that are called spiritual and celestial loves, they are filthy, as they were with that nation which had externals without an internal. The words 'without an internal' are used, and by this is meant no acknowledgement of truth and no affection for good, thus no faith and no charity; for these are qualities that belong to the internal man and from them spring ways of exercising charity, which are external forms of good. The Lord speaks of that internal, when it is devoid of faith and charity and yet full of evils and falsities, as that which is 'empty', in Matthew 12:43-45. This is what 'external without an internal' serves to describe. So then 'the foreskin' means the kinds of love that are very much external; therefore when those kinds of love have been removed, meant by Zipporah's cutting off the foreskin, the actual nature of them is seen, and the internal is accordingly laid bare.

4018. 'In front of the flocks; and they came on heat as they came to drink' means even to the point of an intense desire in the affection for truth that a joining [to the goods and truths within the natural] might be effected. This is clear from the meaning of 'coming on heat as they came to drink' as an intense desire. The meaning of 'being on heat' as an intense desire is self-evident; and for the meaning of 'coming to drink' as the affection for truth, see immediately above in 4017. The reason why 'in front of the flocks' means that a joining to the truths and goods within the natural might be effected is that this phrase implies seeing and consequent arousal of affection, for this is the manner in which spiritual things are joined to a person. What is more, every implantation of truth or good in a person, as well as every joining of them to him, is effected by means of affection. The truths and goods which a person has learned but for which he has no affection do indeed enter the memory, but they are lodged there as insecurely as a feather on top of a wall which is blown off by the slightest puff of wind.

[2] As regards the things that enter the memory the position is this: Those for which there is no affection pass into the unlit parts of the memory when they enter it, whereas those for which there is affection pass into the light there. Things present in that light are seen and appear clearly and distinctly when any matter of a similar nature is brought up, but not so the things lying around in the unlit parts. Such is the effect that affection belonging to love has. From this it may be seen that all implanting of truth and joining of it to good is effected through affection; and the greater that affection, the stronger the tie joining the two together.

[3] The intense desire of the affection is in this case inmost affection. But truths are not capable of being implanted and joined to good except by means of affections for truth and good, which affections well up from charity towards the neighbour and love to the Lord as their sources. But evils and falsities are implanted by means of affections for evil and falsity, and these affections well up from self-love and love of the world as their sources. This being so, and the subject at this point in the internal sense being the joining of good and truth within the natural man, mention is therefore made here and in what follows of the flock being on heat when they came to drink, by which such considerations are meant.
